Hifi Question?

I m planning on getting a Harman Kardon HK 3770. It has bluetooth and dlna, the latter I am not familair with but I do plan on mostly using it for it s bluetooth connectivity to listen to audio from my phone.

According to the specs on the manual I downloaded, it only supports MP3 32-320kbps and WMA ver.9 only.

I don t know if this affects my ability to play flac and other file types via bluetooth or not, or if it only affects files that go through the system via usb and dlna??

Also, If I later purchase a cd component and connect it to this receiver will those limitations prevent me from playing original cd s or cd s which I have burned containing other file types?


I am a total noob

    Don't know about MP3. It is a file compression method that I do not use. CD players and the compact disc format do not compress the music. If you extract files from a CD, you can save them as wav files, which are not compressed. As long as your receiver has RCA inputs, CD players will work. You can in fact plug a CD into any input (except the phono input) such as those labeled tuner, tape, CD, TV, or aux.,  and the receiver will handle them the same way. The signals going in are the same format. Harman Kardon traditionally makes good amplifiers and receivers. They are able to handle the infinity RS speakers I own that have an impedance of 2 ohms. Most Japanese amps and receivers cannot handle such low impedance inputs and they get damaged easily. Japanese amps are designed to handle 8 ohms, so that their power ratings look good without needing to spend money beefing up the power supply to handle the high current demands of low impedance speakers. My speakers destroyed a couple of Japanese made amps (an Akai and a Sony) before I figured out I need better amps for my speakers. They shut themselves down if I turned up the volume to protect themselves from being short-circuited due to the low impedance of my speakers. After many of these shutdowns over time, the amplifiers simply died.

    Well it is a good question and yes the receiver does not play flac files played through the USB port.  Now that is if your going through your recievers DAC.  So you would have to use an external DAC or high res player to play high res Flac files through one of the other inputs 

    From the Manual:

    Listening to Media on a USB Device

    Your stereo receiver is compatible with MP3 and WMA media. No other types of media are supported. 

    • MP3 compatibility: Mono or stereo, Constant Bit Rates (CBR) from 32 kbps

    to 320kbps, Variable Bit Rates (VBR) from lowest to highest quality, with

    sample rates from 8 kHz – 48 kHz.

    • WMA compatibility: Ver. 9.0 standard audio, stereo CBR with

    32 kHz – 48 kHz sampling rate and 40kbps – 192kbps bit rate, mono CBR

    with 8 kHz – 16 kHz sampling rate and 5 kbps – 16 kbps bit rate, VBR Pass

    Encoding and Quality Encoding 10 – 98, 44 kHz and 48 kHz sampling rate.

    NOTE: WMA 9.0 lossless format is not supported

    DNLA is a wifi transmission and will have a better cleaner transmission than Bluetooth. The frequency spectrum is wider and also there is less manipulation and conversion of the files. Bluetooth converts files to another format before transmission which further compresses an already compressed file.. A lot depends on the quality of the files your transmitting and also on the level of Bluetooth your using...Bluetooth 5.1 is suppose to be close to rivaling the quality of sound that  DLNA transmissions can do (near CD quality)...but both transmitter and receiver must have Bluetooth 5.1 in order to achieve such quality otherwise it degrades to the lowest common denominator between the two components.... APTX can also help quality quite a bit but again both transmitter and receiver must have it in order for it to be effective....I have listened to mp3 playback over both DNLA and Bluetooth and DNLA was superior ...But again a lot depends on what your speakers and amplifier are like and and also what version of Bluetooth your using and how intently you listen.

    The restrictions on file types only apply for playing files directly on the unit, whether they are stored on it or read over DLNA from another server.

    If you are sending audio to it that has been decoded on another device - like media on a phone or tablet - then those restrictions do not apply.

    However, as Spacemising says, a high-end system is a waste of money for use with Bluetooth as bluetooth audio uses a "lossy compression" format, so the end quality is restricted no matter what the source. Though if you do add a CD / DVD / Blu-ray as an audio source, a direct connection from one of those or other uncompressed / non-lossy sources will give full quality.

    You need a good in-person advisor. 

    One of the easiest to find would be a home theater installer, 

    although racking up lots of consultation time could get expensive.  


    Bluetooth just plain SUCKS for audio quality. 

    It should be used Only as a convenience. 


    The best value in a music source to complement a decent receiver 

    would be a BD player (go for one that costs over $100, though), 

    which, because of licensing agreements, 

    is required to also play DVDs and CDs.
